The pre-KPB interval: sedimentary record of a major Deccan Traps pulse?

The KPB crisis is one of the major biological crises that affected the Earth at Phanerozoic times. There is still an acrimonious debate on the nature and origin of this mass extinction: proponents of the idea that large bolide impacts caused most of the Phanerozoic mass extinctions are opposed to those who favoured a terrestrial origin linked to continental flood basalt eruptions of the Deccan Traps. The major limitations reside in the difficulty to date with precision the stratigraphic position of Deccan traps pulses since direct markers are still missing.
